 |
|
I'm refreshing a 924 Michael Mount race engine and want to replace the injector plugs which are large Allen head bolts/plugs as they're quite corroded/ugly. (it runs 50 DCO carbs)
Can anyone point me to the proper size/thread/length?
TIA!

When I was modifying heads I fund some I think from Belmetric Bolt. As I recall either 21 or 22mm. Measure with calipers, It is a metric pipe plug. PM sent

Update, 22mm from McMaster Carr get the ones with a sunken hex heads as the flanged one won't seal.

Hmmm, so not too sure about this. I just chased the threads in one of my heads with an M24 x 1.5 tap.
Unless the 22mm pipe thread matches up with that?
